At first, it seemed like the poisoned russian agent might have ingested thallium in the form of thallium(i) sulfate, a rodenticide (rat poison), not allowed in the us and western countries but still used in other countries. thallium leads to hair loss. it also replaces potassium in important enzymes in the brain, muscles and skin. it takes 8.0 x 102 mg of thallium ion to kill an average adult. it took a bit of investigating to figure out that the agent was actually poisoned by polonium, a radioactive element, harmful only if it goes into the body. the radioactivity emitted by polonium, alpha particles, can be stopped by skin; but, if ingested, it gets into the blood stream, travels to organs and does lots of damage. the maximum safe body amount of polonium is 7 pg (picograms! ) the agent was apparently poisoned with about 10 micrograms. to provide the minimum amount of thallium to kill the average adult, how many ml of 0.45 m solution of thallium(i) sulfate needs to be ingested?
